Patented Dec. 31, 1940 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to electric dry shavers, and more particularly toan electric dry shaver having a novel clipper plate supporting means.

Like a number of electric shavers now on the market, a shaver accordingto the present invention works on the clipper principle having as itdoes a stationary clipper plate provided with teeth and a movableclipper plate also having teeth and adapted to reciprocate with respectto the stationary plate. When the plates which are disposed like theblades of a safety razor are drawn across the face, the whiskers will bedirected between the teeth and will be sheared off.

The principal object of the invention is to provide an electric dryshaver with a moving clipper plate narrower than the stationary clipperplate and disposed thereabove.

Another object of the invention is to provide such an electric dryshaver with spring means for holding the movable clipper plate againstthe stationary clipper plate.

Still a further object of the invention resides in providing means bywhich the movable and stationary clipper plates can be easily removedand replaced.

The invention has for a further object the provision of an electric dryshaver of simple construction and which can be manufactured to sell at acomparatively low figure and which at the same time gives an effectiveshave if not better than the electric dry shavers heretofore known.

Other objects of the invention will be more apparent from the followingdescription and accompanying drawing.

In the drawing:

Fig. 1 is an enlarged perspective view of one embodiment of theinvention showing only the upper portion of the shaver to which theinven tion relates. I

Fig. 2 is a similar view with the parts exploded to show the manner inwhich the movable and stationary plates are secured in place.

Fig. 3 is a top plan view of theshaver with the stationary and movableclipper plates and the tensioning means removed.

Fig. 4 is a perspective view of the reciprocating member to which themovable clipper plate is secured, said figure showing principally theopenings in the base of the member.

The electric dry shaver illustrated in the drawing has a handle 2 whichmay be of hard rubber, Bakelite or any suitable insulation material. Thehandle preferably should be comparatively small and narrow 50 that itsimulates as closely as possible the size and shape of the handles ofthe ordinary safety razors. The handle houses a simple electric motor(not shown) which may be of the type used in dry shavers and which isconnected by suitable mechanism to impart a limited reciprocatorymovement to an actuator 4 which extends upwardly from a rectangular wellin the upper end of the handle.

Formed so as to fit in the well is a supporting member 6 of metal or thelike. The member 6 more specifically is in theform of a rectangular boxhaving side and end walls and a bottom wall but no top wall. The bottomwall is provided with a central opening 8 through which theactuatorpasses and the opening 8 is larger than the actuator 4 so as notto interfere with its limited reciprocatory movement. Secured to thebase of the member 6 at equal distance from the center are twosupporting posts Ill and I2 which extend upwardly from the base to apoint slightly above the upper edge of the member 6. These supportingposts are provided with axial bores threaded to receive the screws Mwhich are used for securing the stationary clipper plate l6 to thehandle. The stationary clipper plate is provided with openings I8through which the screws [4 pass. It is also provided with elongatedopen ings 20 for a purpose to be later described.

The reference numeral 22 indicates a reciprocal member to which themovable clipper plate 24 is secured. The member 22 as shown in Figs. 3and 4 is also rectangular box shaped having side walls, end walls, and abottom wall but no top wall. The member 22 is of less length than themember 6 and also of slightly less width as clearly shown in Fig. 3, andit is adapted to reciprocate in the member 6, and its reciprocalmovement is guided by the side walls of the member 6 against which theside walls of the member 22 slide.

The member 22 has a central opening 23 through which the member 4 passesand the opening 23 is only large enough to admit the actuator 4 so thatwhen the actuator is moved by the motor within the handle the member 22is also reciprocated within the member 6. The base of the member 22 isprovided with openings 25 through which the supporting posts Ill and I2pass. These openings 25 are larger than the diameter of the posts l0 andI2 so that the posts do not interfere with the reciprocal movement ofthe member 22. The member 22 is provided at each end at the uppersurface with inwardly extending portions 26 having screw threaded bores28 therein for receiving the screws 30 which are employed for securingthe movable clipper plate 24 to the reciprocable member 22. The movableclipper plate 24 is provided with openings 32 through which the screws30 pass. The screws 3!] also pass through the openings 20 in thestationary plate and these openings are large enough so as not tointerfere with movement of the movable clipper plate.

The movable clipper plate is spring pressed against the stationaryclipper plate by means of a coil spring 34 which normally is of greaterlength than the actuator 4 and which is disposed so as to surround theactuator 4. The lower end of the spring 34 presses against the base ofthe reciprocal member 22, and its upper end is pressed against the lowersurface of the stationary clipper plate I6. Since the movable clipperplate 24 is secured by the screws 30 to the reciprocating member 22, itwill be apparent that the movable clipper plate is spring pressed ortensioned against the stationary clipper plate.

The movable and stationary clipper plates are provided at their endswith teeth 36 and the plates themselves are preferably arcuate in crosssection, although they may be fiat or of some other shape withoutdeparting from the inventive concept.

It will be noted that the construction described is extremely simple andat the same time provides an electric dry shaver in which the movableclipper plate is disposed above the stationary clipper plate in such amanner as to be held against the stationary clipper plate. At the sametime both of the clipper plates can easily be removed for replacement,

Naturally the reciprocatory movement of the movable plate through thereciprocatory member 22 may be effected by means other than the actuatori. For example, the reciprocatory movement may be effected by having arotatable shaft on the end of which a pin is eccentrically disposed.This pin may engage a slot or recess in the base of the reciprocablemember 22.

Obviously modifications of the invention disclosed could be made withoutdeparting from the inventive concept, and I do not intend to be limitedexcept as indicated in the following claims.
